IIy inventionieiatest impr0vements in building constrncticns, and itconsists inthe emnbinations, ccnstrnctions, and arrange- 1nents hereindescribed and c1aimed;

An object of niy invention is to provide a device f0r nse wit-h ccncreteCBIIIIg'S means of which snspensicn bars er rode fcr 1netallathcrsimilar "ceiling 1naterial rnay be quick1y and econc1nically applied.

A nrther cbject is to provide a device of the type described in whichthesnspendiig faciiitating the rapid and accurate placing of saidreinforcingrods.

A 'urther object is te provide 1netahfor1ns which in themselvesform asupport for the reinficrcing rode, therebyobiiating. the use ofadditional supporting members,

ther cbjectjs and advantages will appear in the olicwingSPGCfiLQ1T{ZLII(IIIG novel features of the invention wilibe prticularlypcin ted out in the appended claims.

My invention is illustratedinthe accom panying drawings, formin-g partof this ap: plicatin, in which v Figure I is a side view of one ofthemetal :E0r1ns, the wooden form "upon which it is supported heing shownin secticn,

Fignre2is a sectionai view along the line 2-2 of Figure 1,

Reierring now to the drawings, 1 indi cates a concrete floor which iscast en a form such as a wooden form 2. This is supported inany sutablemannen-as by thesupports 3; Carried by the form 2 areinverted 1neta1trcnghs t which arespaced apart and which may be rernoved after theconcrete is set. Between these troughs, I p1ace a series of cup shaped1neta for1ns like that shownat 5. These f0r1nsare the general shapeshown in Figure 6. The tops 5? are preferablyflat. The sides havegrceves 6 pressed thereinand the bottoms have cpenings 7, Anchoring de-Vices like that shown in Iigure 2 are pre- Vided. These anchoringzdevices consist of a central bowed porticn 8 which is within the form 5.The ends of this portion are prolcne;ed and passed thrcugh the opening 7and then are bent npwardly a nd iie in the groeves Abevethe upper flatsurface 5%, theseanchoring devices are bent outwardly te ferm guidemembers 8.

Bef0re the anchers are placd arcnnd the form 5, asnspendingmember 9 inthe form cf a locp is passed over one end of the anchor and over thecentr-al port1on 8. Th1s -I0op Fignre 4, er it ina-y beol' anysuitableshape to receive tlieparticujiar nenaber which itis designed tosupport. In Iignre 4 I have shcwn"thelccp 9 as slxppcrting a channel ron01 bar 10. In this figure theloop is el ongzted. In Figure 5 the openingin the loep may be circuiar te receive acircnlar rod or penci1 11.

In operation, the 0r1n boards 2 are erected, thetr0ughs 4 placed inposition, and the forms 5 are placed between the tioughs: Theyai*eprefejrably arranged in t wo or more r0ws, as sh0wn in Figure ;6 theiorns of each row heing stagg'ered with respect tothe adjacent r0w. Inorder to h0ld the metal forms to the wooden form, I preferably drive anail 12 down through the top of the form 5 so that there is no danger ofdisplacing the form when the reinforcing rods are being p1aced 0r whenthe concrete is being poured. VVith the 1neta1 forms arranged as shownin Figure 6, the reinfcrcing 10ds 13 are very easiiy applied. The Haringarrns 8 of the anchor form guide' n1eans so that it is only necessary t0drop the rode 13 when the arnrs Wil1 guide thern te the tops of thefor1ns 5,

where they rest. This obviates the necessity of having additionalsupporting n1eans for the reinforcing rods.

When the forms 5 are applied and nailed to the wooden form 2, themovable snspend ing member 9 will be pushed up into the position shownin Figure 2. When however, the concrete has set, and the form boards 2are removed, the snspending member9 Will now drop down and Will slde tothe end of the bowed porton 8 and remain suspended. All that isnecessary in order to hold the bars 10 or the pencil rods 11 is to passthe1n through the loop, as shown in Figure 1.

In constructions Where there is consider able weght, it is advisable touse channel irons 10. The metal lath 14 may be wired or otherwisesecured to the bars 10 01' to the pencil rods 11, as shown at 15 inFigure5.

\Vhen the form boaids 2 are rernoved, it

is not necessary to remove the nail 12. The

letter, however, does not interfere with the suspending member 9, sinceit is placed to-- Ward one end and one side of the form 5, as shown inFigures 1 and 2. One nail is suficient to hold the form in place, and itis an easy matter to take off the form boarcls since the mail iscoxnparatively small.

Tlie construction described above has a number of important advantagcs.As stated,

it forrnsa, means forsupporting the rein forcing rods and for quicklyplacing them in position. It enables the for1ns 5 to be placed directlyon the form boards 2 since the suspencling member 1noves Within the form5 to perrnit it. It obviates the necessity of tying the bars or rods tothe suspendng member, but permits them to be thrust throughthe alignedloops, where they are held securely. The flaring outwardly of the 1r1ns8 serves the double function of guiclng the reinforcingrods into theirpositions on the tops of the f0rms 5 and then, when the concrete hasbeen poured, they have tl1er normal functions of anchors for thesuspendng means 9.

I am aware that metal for1ns like that shown at 5 having suspendingmeans is not broadly new, but ordinarily the lath or rods have to besecured to the suspendin means by tying or in some other way end do notconsist of loopls through which the bars or rods may he t rust, n01 dothe forms serve the purpose of supports for the reinforcing rods nor dothe anchors serve as guides or putting the rods in place.

I claim: 1. A building construction, comprisng a concrete ceilin havinga plurality of cup shaped metal or1ns embedded in the lower surfacethereof, certain of said or1ns being in axle alignment, 2i U-shapedanchor '0I eaoh form, said anchor having a central bowed portiondisposed within the form, and anguiarly disposed guide portions ab0veand to one side of the top of the form, and a sus" pending loop carriedb y said central portion.

2. A building construction, comprising u concrete ceiling having aplurality of cupshaped lnetal for1ns embedded in the lower suri'acethe1e0f, certein of said forms being in axile alignment, a U-shapedanchor for each orn1, said anchor having a central bowed portiondisposed within the form, and angularly dsposed gude portions above andto one side of the top of the form, and a suspending loop carried bysaidcentral portion, said loop having en opening for permitting an upwardmovexnent wthin the. form or a downward movement to bring the loopbelo.w the lower edge of the form.

3. Abnildingconstruction, co1nprsing a concrete ceiling havng aplurality of cup sh1ped metnl fornis embedded in the lower surfacethereof, certain of said forrns being in axile alignrnent a U-shapedanchor for each form,- said anchor having .a central bowed portiondisposed within the form, and angularly disposed guide portions alooveand to one side of the top of the form, and a suspending loop carried bysaid central porton, said loop having en opening fox permitting an upwrdmovement withn the form or a downwardmovement to bring the loop belowthe lower edge of the forrn and a la thsuspending memloer arranged to bereceived and be suspended by the loops of certain of said aligned forms.
